There’s a good chance you used to talk in your sleep too: 20% of people have been sleeptalkers at some stage in their lives.
Sleeptalking can happen any time, but it usually happens in the earliest stages of deep sleep, so even if you can get your child into a sleep conversation he probably won’t remember it in the morning.
Your child may sleeptalk more regularly if he is excited or worried about something, such as a concert, a holiday or a test. Talking with him about the event in a calm and supportive way might help reduce his night-time chatter.
Sleeptalking doesn’t harm your child. But it can be annoying for anyone who shares a room with him. If it keeps other children awake, you may have to change the sleeping arrangements.
Talking during sleep doesn’t mean that your child is worrying about anything, or that he has psychological concerns. But if you want to double-check, talk to a professional.
